Examples and Use Cases
Learn how to use ImproveFast in real-world scenarios.
▸ User:
I'm writing marketing emails and want to test which subject line style gets the best open rates. I have three approaches: "question-based" (e.g., "Ready to 10x your sales?"), "direct-benefit" (e.g., "Get 10x more sales"), and "curiosity-gap" (e.g., "The secret to 10x sales"). Can you help me run an experiment using ImproveFast?
◆ Claude:
I'll help you set up an experiment to find the best subject line style. Let me use the ImproveFast MCP server to initialize this.

Great! I've created experiment abc-123. Now, each time you send an email campaign, I'll tell you which style to use. Then you report back the open rate (as a score from 0 to 1), and the system will learn which style works best.
▸ User:
Perfect! Which style should I use for my first campaign?
◆ Claude:
[Using select tool with experimentId: abc-123]
Use the question-based style for this campaign.
▸ User:
The question-based email got a 23% open rate. That's 0.23 as a score.
◆ Claude:

Recorded! After 50-100 more trials, we'll know which style consistently performs best.

I'm a sales rep and want to figure out which pitch angle works best for our product. I've been trying three approaches: focusing on "cost savings," highlighting "time efficiency," or emphasizing "competitive advantage." Can you use ImproveFast to help me test these?
◆ ChatGPT:
Absolutely! I'll set up an experiment to track which pitch angle gets the best results. Let me initialize this with your three variants.

Done! I've created experiment xyz-789. For each sales call, I'll recommend which angle to use. After the call, just tell me if they converted (1.0) or didn't (0.0), and the system will learn which angle works best.
▸ User:
Got it. I have a call in 10 minutes. Which angle should I lead with?
◆ ChatGPT:

Lead with time-efficiency for this call. Emphasize how much time your product saves them.
▸ User:
They said yes! They're signing the contract tomorrow. Score: 1.0
◆ ChatGPT:
[Using record tool with variant: time-efficiency, score: 1.0]
Excellent! Recorded. Keep tracking your calls over the next few weeks, and we'll know definitively which angle has the highest close rate.
▸ User:
I run a tech blog and want to figure out which content format gets the most engagement. I've been experimenting with "how-to tutorials," "case studies," and "opinion pieces." Can ImproveFast help me find which format my audience prefers?
◆ Claude:
Perfect use case for ImproveFast! I'll set up an experiment to track which format drives the best engagement. Let me initialize this.

Experiment def-456 is ready. For each blog post you publish, I'll suggest which format to use. Then report the engagement score (you could use time-on-page, shares, or a composite metric normalized to 0-1).
▸ User:
Great! I'm planning my next post for tomorrow. Which format should I write?
◆ Claude:
[Using select tool with experimentId: def-456]
Write a case-study for your next post.
▸ User:
The case study got 4.2 minutes average time-on-page and 47 shares. Based on my metrics, that's a 0.78 engagement score.
◆ Claude:
[Using record tool with variant: case-study, score: 0.78]
Recorded! That's a strong score.

After 12 posts so far, case studies are leading (0.76 avg), followed by how-to tutorials (0.68 avg) and opinion pieces (0.52 avg). Keep going — we need about 50-150 total posts for statistical confidence.
